It relates to various preferred techniques such as methods and apparatus used in the field of patient treatment with humidified medical gases. The invention includes a humidifier and a method of operating such a humidifier, in particular a method of adapting the operation of the humidifier, preferably automatically, a humidification chamber, a method of manufacturing such a chamber, and A method and apparatus for temperature controlled electrical heating of a tube assembly for medical gas is included.

Hereinafter, for the preferred technology of the present invention, a general humidifier, a humidifier chamber with illumination, a tube assembly for medical gas, in particular a temperature-controlled electric heating of the breathing tube, and a breathing tube Heating and / or control devices and / or improved sealing of the bottom and / or lid of the humidifier chamber. It will be readily apparent that the different features of the individual technologies discussed here will be combined to obtain a preferred solution.

  Various technical solutions are available for the heating and humidification of medical gases, in particular artificial respiration and respiratory therapy, and continuous or intermittent spraying into the respiratory tract, body cavities, organs, each of these solutions Is optimized for a specific application.

  Heating and humidification of medical gases, especially for artificial respiration, respiratory therapy, and heating or humidification for continuous or intermittent spraying into the respiratory tract, body cavities, and organs, due to dehydration and cold symptoms for several years It is recognized as necessary in various situations to minimize side effects.

  A number of so-called respiratory treatment devices, such as CPAP and bi-level systems, are commonly marketed for the treatment of sleep-related respiratory diseases, making the distinction from so-called respiratory devices increasingly obscure. It is also known that patient comfort and treatment success are improved by humidifying the supplied breathing gas. For this reason, there are many humidifiers that can be combined with the above respiratory treatment apparatus. It is known that the effect of humidification can be significantly increased by heating the water.

  In general, an electronic diagnostic control, management, and operation unit (hereinafter referred to as a humidifier), a humidification chamber that saturates gas containing water vapor (the shape of the humidification cylinder, etc. is arbitrary), typically An active breathing gas humidifier comprising at least one heated breathing tube is utilized.

The following solutions are well known for heating and humidified medical gas, especially used for artificial respiration and respiratory therapy.
1. Passover humidifier (eg Fisher & Paykel) optionally combined with evaporation core and / or bubble
2. Counterflow humidifier (Grundler HumiCare)
3. Fluid contact using thin film (eg Drager Aquamod)
4). Instantaneous evaporator (eg Pari Omni Hydrate)
5. Bubble humidifier (eg, Wilamed)

  Various types of humidification and humidification concepts are discussed in EP 1 558 877 A1, the contents of which are incorporated herein by reference.

  In some of the embodiments described above, the apparatus for humidifying the breathing gas comprises a central unit with a control and operating unit, a humidification chamber, and optional auxiliary equipment such as a heating tube. .

  Currently, if a user selects a certain product, he / she is bound by a certain humidification technique. It limits flexible usage, and each technology has advantages and disadvantages (eg, in terms of tradeability, operability, functionality) compared to other technologies.

  Moreover, the humidifier described above is always coupled to the power supply unit, which is usually centralized in the central unit. As a result, this cost intensive assembly must be configured for the electrically most energy intensive application of possible devices. If the device is used exclusively for applications that require significantly less energy than can be supplied in terms of the size of the power supply unit, this can have a significant impact on the size and weight of the power supply unit. And limit cost efficiency.

  So far, the above solution can supply power to at most two external heating components and control them. Depending on the intended use, additional control devices are needed to control additional components of the application (eg, heating color used for heating filtering collars, valves and / or sensors).

  None of the above solutions provide an interface that allows partial or complete (remote) control by connecting a device such as a monitor or remote operation of such a device by a humidifier. So far it is only known to combine a breathing device and a humidifier for the purpose of data transmission (such as gas flow rate etc.) (eg DE 10 2006 045 739 B3).

  Moreover, the solutions known in the art are generally difficult because they are less flexible and therapeutic.

  The humidifier may include a user interface comprising an LED signal and sound generator and / or a 7-segment display or a modern device graphic display.

The humidifier chamber is a normally disposable or reusable canister made of a transparent plastic material and in intensive contact with water and gas. In many cases, even in a system having an automatic water level adjustment function, the user must monitor an appropriate water level by visual inspection.

  There are also humidifiers that detect the water level in the chamber optically or by other sensors.

  Current warning signals and alarms are transmitted in different ways through the user interface of each device. Depending on the environment in which the device is used and the structural design, it may be difficult to identify the device that will issue the alarm immediately and accurately. This is true when the same device is used several times in the same room.

  In current humidification chambers, the water level can be detected. For example, a magnet float can be used to detect high water levels. When the water level is too high, the magnet float triggers a magnet switch installed at each location of the humidification chamber, and a full water alarm is transmitted. This solution technically results in material consumption (each individual humidification chamber requires a separate magnet switch), which causes the cost of the humidification chamber to be high.

Current humidification chambers use various concepts to limit bacterial contamination. The basic concept is to limit the usage period of the chamber and / or to provide a prescribed or recommended treatment (in the case of a reusable humidification chamber). These concepts have drawbacks. For example, from the perspective of a patient who has been artificially ventilated for a long time, both concepts have to open the respiratory circulation to replace the humidification chamber, which is certainly a sanitary disadvantage (during the exchange). the main cause and Turkey to penetrate bacteria in open inlet).

In current humidifier chambers, the temperature is placed directly in the medium (gas or fluid) and inserted in a manner that seals the humidifier chamber or as a component tightly integrated into the humidifier chamber Measured by. Solutions with sensors inserted are disadvantageous because they cannot be realized with one concept of use and form a potential entrance for pathogens to enter. Solution sensor is integrated with respect to it, this solution is technically complicated and requires a lot of material.

Various technical solutions are known for heating and humidifying medical gases, in particular for artificial respiration and respiratory therapy, and for laparoscopy. Electrically heated breathing tubes, particularly in combination with so-called active humidifiers, are widely prevalent and are well documented to minimize the production of concentrate in the tubes. These tubes are typically connected to the humidifier by plug-in electrical connections and are supplied with heating power according to regulation and monitor function. There are various types of heating type tubes, and there are those in which the heating coil extends linearly or spirally inside the tube, and those in which the wall surface of the tube itself is heated. In either case, the heating power of the inspiratory tube is controlled based on a temperature sensor located outside the heating area near the patient and protruding into the lumen of the tube. Also, in a very simple embodiment, a preset heating power is output to the heating conductor in the tube and no temperature control is provided. Heating the inspiratory tube is primarily useful for maintaining the proper temperature / humidity, while heating the expiratory tube is primarily useful for preventing the formation of concentrate in the breathing system and thus the end of the heating section. It is not so important that the temperature is constant in the part.

  Since the temperature of the heating tube is controlled by a sensor at the end of each heating section, essentially the temperature of the flowing gas is detected by the sensor. If the gas flow is interrupted for a relatively long time, there is basically a risk that the corresponding tube will be overheated or heat storage will occur there. Prior art using temperature sensors cannot adequately detect the risk, especially those systems do not use fluid sensors.

  Also, according to commercially available solutions to this problem, the fluid sensor is also integrated into at least one gas guiding element. For example, integrated in the expiratory limb, the sensor detects gas flow interruptions accurately and quickly. In this regard, such sensors have the problem of being relatively expensive and are difficult to implement in a disposable type from a commercial point of view.

  Furthermore, this solution has only been realized with limbs extending from the humidifier chamber towards the patient or from the breathing apparatus towards the chamber. However, it cannot be realized in the reverse direction (eg, from the patient to the breathing device exhalation valve). However, due to severe leaks or changes in breathing settings, there is a daily situation where there is sufficient gas flow in the inspiratory limb and / or humidification chamber, but the gas flow is stopped only in the expiratory limb. Get up.

  In contrast, when the breathing device is turned on or after interrupting breathing, the user forgets to turn on the humidifier, so that the humidifier's electrical functions cannot be used and the switch is turned off. Not only can the task not be executed, but the corresponding alarm cannot actually be sent out.

  The high absolute humidity of the medical gas increases the risk of forming a concentrate on the breathing tube and patient interface, which can occur, for example, when noise occurs or the temperature of the bedroom decreases, especially during the night. Causes inaccuracies that cause inaccurate medical device measurements. Such defects are addressed using means such as thermal insulation and / or heated tubes. It is known as a unit that maintains breathing in an enhanced manner.

  Most respiratory therapy devices and humidifiers do not have a controller to control the heated breathing tube in an integrated manner, especially if they do not have temperature control, the patient / user will condense when using the device. Things will be difficult to produce. For this reason, high-performance devices with integrated solutions with heated tubes exist, but doctors prescribe inexpensive standard devices without tube heating, so patients do not have such high-performance devices Is rarely used.

  Further applications where unwanted concentrate formation occurs during use are to aid in the use of cardiopulmonary bypass or pump-free lung function, where blood flows outside the body through an exchange membrane through which gas flows through the other side There is use of the system. Concentrate formation occurs on the gas side, causing an increase in pressure loss on the gas side and a decrease in the exchange surface. Also, both problems can be avoided by using the heated tube of the present technology.

Currently, humidification chambers that are on the market have a housing (sealing) member that seals the bottom surface of the housing and the chamber together (for example, a member formed of an adhesive, an O-ring, It is customary to connect using an additional sealing member such as a specially shaped elastic member. This additional seal member can be firmly joined to any of the components (eg, two-part injection molded parts). Such a structural approach has the disadvantage that a sealing member has to be added. Therefore, it is necessary to increase the material, which increases the complexity, and therefore there is a risk that the robustness is reduced due to the failure of the component. In addition, manufacturing costs and complexity increase, and the set failure and defect rate tend to increase. In such a structure, the pressure exerts a load on the seal surface, and if the pressure continues to act, there will be signs of wear, for example, in the form of a water leak or its increase. An example of such a chamber is for example EP 0589 491B1.

  The present technology provides an improved humidification chamber and an improved method for manufacturing the humidification chamber. In particular, the disadvantages of the prior art are overcome or at least improved.

  Embodiments of the present technology describe universal modular devices that can be configured to meet specific requirements, particularly for each individual application. Also described are methods for adapting to the specific humidification required, preferably automatically.

  An apparatus according to the present technology includes at least one of the following features.

  The improved medical gas humidifier, alone or in combination, has improved the range of use, material consumption and functionality, and expanded its application.

  This technology allows the use of humidifier units to select and use humidifier chambers using a variety of technologies, as well as a wider range of applications for a variety of humidification applications. External interfaces, external power supply unit connections, and external secondary batteries can also be used.

  Thus, the apparatus using the present technology is an apparatus (hereinafter referred to as a humidifier) that can be used for any application used for heating and humidifying medical gas, and the apparatus is a humidifier equipped with an electronic control or control unit. It consists of any heating component such as a humidifier unit or humidification module, a humidification chamber adapted to be coupled with the control unit, a breathing tube.

As an example, a method of separation / non-separation from a medium using a humidifier chamber based on the principle of passover and a thin film that can be used by adapting to the operation and control algorithm used in each technology. Various types of chambers using forced (electromechanical) water movement using are described. Various humidification concepts are utilized in the present invention. For example,
(1) Passover humidifier (eg DE 3830314)
This humidifier uses a water tank filled with heated water. The breathing gas becomes a humidified gas as it passes through the surface of the heated water.
(2) Thin film humidifier (eg DE 4303645)
Inside the humidifier, gas passes directly through the surface of the structure protruding from the heated liquid. This structure sucks up a liquid from a water storage tank in which a necessary amount is accumulated, for example, by capillary force. The water in the reservoir is replaced with freshly heated liquid.
(3) Fiber humidifier (eg DE 19727884)
This humidifier incorporates a bundle of fibers (for example, PTFE fibers) having cavities that can partially pass moisture, and the gas is heated and humidified by directly passing through the bundle. Another surface of the fiber is in contact with the liquid needed to humidify .
(4) High-temperature humidifier (eg DE 4312793)
The humidifier vaporizes a small amount of liquid at a temperature of 80 ° C. to 130 ° C. and mixes it with the gas stream. Thereby, energy required for heating and humidifying the gas is supplied.
(5) Bubble-passing humidifier (eg DE 3730551)
In this humidifier, gas passes through the heated liquid as bubbles. As a result, the gas is heated and humidified.
(6) Ultrasonic atomizer (eg DE 197 26 110)
This nebulizer uses ultrasonic waves to vibrate the liquid, generate tiny water droplets, and flow into the gas.
(7) Pressurized sprayer (eg DE 28 34 622)
This sprayer sprays liquid in the form of tiny water droplets, not liquid molecules.
(8) Heated steam converter (HME, eg DE 94 17 169), filter pad, etc. (artificial nose)
In this device by passing through the surface of the gas is wet remarkably direct, the gas is water vapor saturated. This “ artificial nose ” extracts heat and moisture from the patient's exhaled gas. The filter pad uses air conditioning technology to obtain heat and moisture from a tank or similar device. While the gas is heated and humidified, the filter pad filters it out of the particles in small amounts.
(9) Amplifying device (eg DE 44 32 907)
This device supplements the inadequate capacity of the “artificial nose” (HME) by adding liquid and water. This requires electric circuit control technology.
(10) Combination with the above system (eg DE 296 12 115)
In this combined system, the gas is first overheated and humidified. At this time, in the next second stage, the temperature is lowered to a desired temperature by a metal thin plate or the same performance. During this stage, saturated moisture forms water droplets on the metal sheet. This water droplet is recirculated to the humidifier.
(11) Humidifier (eg, DE 37 35 219) that humidifies ambient air using a multilayer rotating plate
This system has a mechanism in which a multilayer rotating plate is immersed in water while the rotating plate rotates. Meanwhile, the blower is sending gas to the multilayer board. This device keeps the gas clean against small foreign objects and moisture. These systems require non-volatile additives in the liquid to reduce the surface tension of the liquid so that the layers of the plate are sufficiently wet.
(12) Counterflow humidifier (eg, EP 1558877)
A humidifier in which water and gas move in opposite directions through a large countercurrent exchange surface.
(12) Other types of humidifiers.

  Although it relates to specific humidification methods and concepts, the humidification concept referred to above with respect to prior art similar to EP 1 558 877 A1 which provides a humidification concept known from other references and a summary thereof is also shown. It is. The contents of which are incorporated herein by reference.

  Embodiments include at least a control and adjustment unit with an interface for the humidification chamber so that various technology and concept chambers can be utilized.

As an embodiment, the chamber and the humidifier communicate with each other by a method of transmitting information for identifying individual characteristics by wire or wireless. Therefore, control / adjustment algorithms, monitoring and alarm functions, and user interfaces are automatically adjusted. Further, the adjustment can be performed manually, and the adjustment can be performed by the user.

  In addition to the operations described above, some embodiments may adjust parameters depending on the chamber and its application. For example, monitoring of the maximum expiration date of each humidification chamber, desired temperature of the heating plate, priority distribution of power when insufficient power is supplied from the power supply unit (for example, secondary battery provided in countercurrent chamber) Inhalation tube and expiratory tube heating priority placed opposite each other).

In one embodiment, amplitude and frequency modulated electromagnets are implemented through magnetic coupling as a drive for various types of water movement and are integrated into a humidifier. Therefore, it is possible to operate a counter-current evaporation chamber and a pass-over chamber that are selectively provided with water moving means added by magnetic coupling (a combination of several independent water moving means). Thereby, if necessary, the temperature gradient between the bottom surface of the chamber and the surface of the liquid can be suppressed. In another embodiment, there is a chamber that is driven by separating a liquid and a gas with a semipermeable thin film.

  As an example, the intensity of water movement varies based on user adjustments as well as operating parameters (eg, average gas flow rate). Therefore, electro-mechanical energy is exclusively used for circulation and movement (in contrast, bubble humidifiers are generally realized using the energy of compressed air).

Heat energy is transferred from the humidifier to the water for humidification by a heating plate with a general temperature control installed on the bottom of the humidification chamber made of metal or resin. Also, when it is necessary to humidify near the patient, the heat energy is transmitted using means such as an external interface with a heating element. In this case, the necessary water is supplied from a water reservoir to which a pump is coupled (for example, coupled by magnetic action). The water tank is connected to or separated from the humidifier. The water may be heated by magnetic induction or radiant energy.

  The humidification chamber contains an integrated sensor, which may be inserted for control purposes. The device and the humidification chamber are provided with corresponding interfaces for this purpose.

In an embodiment, the power supply unit is installed as a separate assembly. Thereby, the installation place of a humidifier falls below on the relationship with the gravity of weight, and there exists an advantage also as a movable application, for example . In addition, if the power supply unit is installed in a separate assembly , a small space near the patient can be used efficiently, so that an actual humidifier can be significantly miniaturized. In one embodiment, the power supply unit is recognized by the humidifier and the operation thereof is adjusted by wired or wireless communication. In an embodiment , a secondary battery having similar recognition characteristics may be connected instead of the power supply unit.

Since the humidifier is aware of the specifications of the connected power supply, limit the output power of the humidifier or by adjusting to give automatically the priority if necessary, excessive heating or overload can avoid. Such power management, in such a way that logical Ji is in the content of WP 2010/028427 on September 7, 2009, preferably made, the entire contents of which are incorporated herein. For example, if the device can be used and heated for a relatively long period of time, it can use a power supply unit that moves at a slightly higher amount than the permanent power required and during the heating time , smaller than the high output is required apparatus can be reduced in weight.

Furthermore, as an external element for sending and controlling information, a humidifier equipped with at least one, preferably three interfaces, is given as an example. These interfaces, components in respiratory circulation gas flows, such as filter, sensor and the valve, in order to concentrate is prevented from generation to be provided to the heating tubes or heating collar.

Furthermore, any of these interfaces can be implemented and there is an embodiment in which the output power can be measured by a humidifier, thereby avoiding overloading of the power supply unit or the control unit itself, or Applicable output is possible.

In addition, there are interfaces that can communicate with other medical devices, such as a USB interface. In particular, control commands can be communicated with each other via these interfaces, for example, a humidifier user interface may be used to operate another system.

In some embodiments, not only the operation of the gas flow generator or gas mixer is specifically intended, but also a configuration such as a combination of a monitoring system, respiratory device, and respiratory treatment device to communicate the patient's body temperature to the humidifier There has been further possible. The latter case has the advantage that the breathing device interface can be used to remotely control the humidifier. Such a configuration eliminates the need for operating components configured in the humidifier, and such a configuration is different from the configuration described in DE 10 2006 045 739 B3.

Another and / or additional feature of the technology is a humidified chamber that is illuminated with UV light or infrared light to improve the quality of water in the visible light and hygiene, and adapted to detect operating conditions medical gas humidifier equipped with a detector that is associated. Each means for sending a signal is also shown.

  One feature of this technology is the development of advanced technology to reduce bacteria in the humidification chamber, which is described in detail below.

Another feature of this technology is the advanced development of technology for realizing non-contact temperature measurement.

  The apparatus of an embodiment includes at least an apparatus composed of a control and operation unit (humidifier), a humidifier chamber, an optional heating tube, at least one lighting unit, and an optical interface. The color appearance and brightness can be adjusted to suit each user's environment (light room and dark room) by the user or automatically (designed using RGB-LED, for example) thing).

  In one embodiment, the lighting unit is utilized to help visualize warning and alarm signals. For example, a warning LED of a color suitable for the operation part may cause the chamber to flash for a moment or emit light simultaneously.

As an example, an improved ability to control the internal bacterial humidified chamber, bacteria, viruses, wavelength suitable thereto to break the DNA of unicellular organisms is selected, with a UV source, the humidifier Ya There is a humidification chamber. A prerequisite for making the water entering the humidification chamber effective and aseptic is an optimal structural arrangement of the radiation source used in the humidification chamber, particularly related to radiation and, if necessary, the seal. In addition, to protect patients, users and others, there are reliable and appropriate defenses that can prevent them from leaking and accidentally bathing or reduce them to an acceptable level. Is provided. The ultraviolet radiation source is operated permanently or intermittently. The sterilizing effect of ultraviolet radiation is particularly effective when the water to be sterilized is moving and agitated, and it is effective for various humidification methods (for example, countercurrent evaporation). It is. When using ultraviolet radiation, it is necessary to choose a suitable material that will not be damaged during the intended expiration date under the influence of radiation.

Furthermore, in one embodiment, information from the illumination of the humidification chamber is collected by measuring the reflection of light by a non-contact method with a sensor provided in the apparatus . In particular, temperature information of liquid and gas can be known. For example, an infrared radiation thermometer that can optically measure the surface temperature, a so-called thermocouple, or the like can be used.

  When using partially transparent tubes, examples include that the humidification chamber can be illuminated selectively or additionally on a portion of each tube.

There is nothing specifically excluded from the sizes, shapes, designs, selected materials and technical concepts of the components described above and as examples. Therefore, selection criteria known in the application field can be used without limitation .

There is at least one embodiment where a humidification chamber is provided with an encoding element that can be read by a humidifier, so that illumination such as UV radiation sources and non-contact detectors are automatically adapted to the respective design of the chamber. Adjusted to

  In practice, one or several or all of the above-described features and functions can be configured individually or in combination. Therefore, many combinations can be specifically realized.

In some embodiments, viewing the Satoshika signal humidifier transmits positively, there is humidified chamber the user information and warnings are provided.

This technology improves the transmission and recognition of visual signals. The visual signal is amplified by using the humidification chamber and the liquid contained therein, and the improvement is helped.

Another additional feature of the present technology is a method and apparatus for temperature controlled electrical heating of a medical gas tube assembly (especially a breathing tube). In particular, this technology relates to a method for protecting the fail-safe function and a method for preventing overheating of the heating tube and related devices and systems.

In one embodiment, at least one temperature sensor with at least one control and operation unit (below a humidifier because it is included in a typical humidification module) is installed at the end of each heating section. Constructed as a means or device for a medical gas heating tube, in particular a breathing tube, with a heating tube.

In one embodiment, there is a method and apparatus for detecting whether there is sufficient gas flow in the heating tube. For example, the gas conduction component can be monitored using periodic fluctuations (preferably a decreasing trend) of the heating power and evaluation of the temperature response curve to automatically avoid heat build-up of components that are not flowing gas.

In one embodiment, (although usually a component of the respiratory gas humidifier, independent to a component also technically possible) Temperature control how heating control device is configured of a heating tube used as Ya in equipment, the control device always choose one aspect of three states.
・ "Sufficient gas flow"
・ Insufficient gas flow
・ "Unknown gas flow"
It then controls and responds according to the following adjusted method .

1. When the heating tube controller is “sufficient gas flow” or “unknown gas flow”:
When exceeding the threshold value heating power of the high output is continuously output, the output power in order to evaluate in accordance with the deviation which gave intentionally caused the temperature curve is intermittently lowered in a short time. The characteristics (interval, time, deviation) of this process are successively used to prove the effectiveness of the results until a sufficient gas flow is clearly detected or removed based on the combined interpretation of the respective temperature responses. A plurality of processes are gradually executed and adjusted and calculated according to the environmental temperature. When an “insufficient gas flow” condition is indicated, the heating of the tube is switched off and the heating power is reduced to a minimum value until gas flow is detected again. (See 2 below)

2. When the heating tube controller is in an “insufficient gas flow” state When a high power heating power is intermittently output in a short time, a temperature response curve is calculated for this deviation. The characteristics of this process (interval, time, deviation) are used to verify the effectiveness of the results until sufficient or insufficient gas flow is clearly detected based on the combined interpretation of the respective temperature responses. A plurality of processes are gradually executed and adjusted and calculated according to the environmental temperature.
If a “sufficient gas flow” condition is indicated, the heating of the tube moves again (see 1 above).

With respect to the above, while averaging, the heating power output is reduced for a relatively long time so that heating of the heating tube is removed (since avoiding heat accumulation is an important detection objective) ) It is an important condition .

  The detection of the gas flow is notified by being displayed on the user interface of each controller.

  According to a further embodiment, the control device reaction such as a warning signal when the gas flow is stopped / restarted or the humidifier is automatically restarted from the standby state immediately after the gas flow is detected is used by the user. It is adjusted by.

Another and / or additional feature of the present technology relates to improvements in the method of manufacturing the chamber as well as improvements in the humidification chamber. In particular, is related to improved sealing methods between a medical gas humidifier, especially medical gas humidifier for use in the treatment of sleep disordered breathing (SDB), a metallic base part and humidifying chamber of the plastic parts . Another feature relates to the method of welding the lid of the humidification chamber.

  As an example, an improved humidification chamber and method of manufacturing the same is described that overcomes or at least improves the disadvantages of the prior art with the present technology.

And a one embodiment, there is exclusively a method and apparatus for achieving the method of sealing by a bottom part made of metallic fitted with an elastic force to the resin of the mating parts. This eliminates the need for additional sealing parts.

  In the embodiment, the seal portion is circular. However, other shapes are also possible.

Further, in an embodiment, the seal is designed to be firmly fixed by itself by changing its shape when pressure is applied, that is , because of its shape, it engages deeply with the mating part of the seal. It has become.

In one embodiment, the bottom part is preferably made in a three-dimensional shape with beads by deep drawing, hydroforming or equivalent methods. Furthermore, the bottom part is made to contact at a suitable angle to the wall of the resin part, mainly inside the cylinder in the area to be sealed, and / or larger than the inside diameter of the cylinder when not assembled. When made and assembled, it preferably stretches substantially due to elasticity.

To improve the quality of the seal after the pressure is applied, in order to continue the automatic sealing step, is desirable Ru over sufficient excess pressure in a humidified chamber in a short time.

  As an example, a mechanical locking structure may be provided under the bottom part to prevent the bottom part from coming off if the chamber water pressure is excessive.

  In practice, it may be configured independently or in combination by one or more or all of the features and functions described in this document. Therefore, many embodiments can be realized.

In addition, this makes it possible to use a smaller, lighter and cheaper power supply unit that increases comfort, cost, usability and the like.

Specific humidified chamber 120 and / or sensed operation modes and algorithms which have been adapted by the humidifier with the present technology based on the power supply pack is automatically adapted, control function, warning function, the user input function (based on the connected humidified chamber that accepts input by a specific user as required for a particular operation, requests), power function, and the like priority control operation function.

Depending on the preferred mode of operation, it is whether the humidifying module 100 detects is operated by an accumulator. If this is the case, the following operating parameters are automatically applied. If heated or the exhalation and inhalation hoses do not reach the target temperature, no audible or visual warning signal is emitted (as opposed to the operation of the grid-connected power supply unit ). Here, it is assumed that technical malfunctions do not take precedence, but the environment may be cooler as long as the battery does not provide enough energy to compensate for the cooler environment.
Also, to prevent condensate, the water temperature is automatically lowered to be below the actual temperature of the intake hose.

Depending on the preferred mode of operation, if the power supply unit does not supply enough power, the maximum power that the unit can supply is detected. Limiting and prioritizing different users , especially heating means (heating plate, hose heating, additional heating elements) prevents power pack overloading. Furthermore, there is no guarantee that a concentrate will be produced in the hose or tube.

Also, the present technology is in line with the above discussion, preferably a humidifier set comprised of a humidification module 100, a humidification module controller, a humidification chamber, a humidifier, for any of the features discussed herein. Similarly, with at least two humidification chambers, preferably, as discussed above, the at least two humidification chambers are preferably directed to humidifiers equipped with different types or different humidification concepts. This may include changing the humidification concept to achieve the best compliance, making specific adjustments to the treatment by simple replacement of the humidification chamber , so that, for example, comfort or similar, treatment identification There is a particular advantage in that it allows taking into account the patient's specific needs with respect to the requirements of the patient .

The present technique is preferably automatic, relates to an advantageous method for the adaptation of the operation of the humidifier. Such methods include humidifier equipment, such as at least one humidification chamber, preferably automatically selected and adapted according to the type of humidification chamber sensed and the power supply unit, and a control algorithm.

According to a preferred embodiment, the humidifier of the present technology uploads and changes humidifier settings, such as various operating parameters of the humidification module controller and / or a control algorithm, preferably stored in a storage device. Provide additional interfaces, such as USB interfaces, to allow . With this configuration, secure updates for improved keeping the humidifier in response to changes in various humidified chamber and the like of the operating requirements described above to date have been allowed.

FIG. 2A shows a perspective view of a preferred humidification chamber 120a , which is a humidification chamber to which the so-called countercurrent humidification described above is applied. The humidifier includes a gas inlet 122 and a gas outlet 124 connected to respective hoses leading from a blower unit (not shown) and to a patient interface (not shown). The humidification chamber 120a additionally includes an interface corresponding to the interface of the humidification module 100, which is further discussed in detail herein (not shown). Positioning such interfaces include the mechanical interface 126 for providing information on the connection and the chamber 120a in a humidified chamber 100. Furthermore, the humidification chamber 120a includes an electrical interface 112, optical interface 116, mechanical or sensor and interface cooperating with heated interface 106 of the drive interface 114, and / or the humidifier 100 is a magnetically. FIG. 2B shows that the humidification chamber 120 a is connected to the humidification module 100. FIG. 3A shows different humidification chambers 120b applying the above-described passover humidification , with different humidification concepts, according to the preferred embodiment described herein . The humidification chamber 120b corresponds to an interface to information provided to the humidification chamber 120a as described above. FIG. 3B shows that the humidification chamber 120 b is connected to the humidification module 100. The humidification module 100 is adapted to automatically detect certain types of other connected humidification chambers and appropriately select operating modes and parameters, as discussed in more detail herein.

  A special reference is made to FIG. 1, which shows a perspective view of the humidification module, which is referred to the above discussion as a universal humidifier.

As can be seen in FIG. 1, the optical interface 116 is positioned toward the humidification chamber to be connected to the humidification module 100 (eg, FIGS. 2B, 3B). The light emitted from the optical interface 116 illuminates the humidification chamber 120, which is configured to be illuminated and is preferably translucent or transparent. It is not necessary humidification chamber 120 is always completely transparent, but this is able to be readily understood that particularly advantageous, for example, a particular advantage of the fact that the humidification chamber translucent is illuminated it may be the one to meet.

By doing so, light emitted from the optical interface 116, refracted or, or dispersion, may be or is corrected. The housing of the humidification chamber 120 and the liquid contained therein, such as water , contribute to the dispersion and diffusion of light received from the optical interface 116 in particular. This results in a more bright, having a light emitting surface, generally fully lit humidified chamber. This is especially, in particular increasing the visual recognition of the information provided by the optical interface 116.

Along the above-described concept of universal humidifier, but the concept is that apply to this aspect of equal technology, humidifying module 100, the connected humidified chamber advantageously it, after sensing, An optical signal may be provided through an optical interface 116 that is specifically adapted to a particular humidification chamber 120 connected to the humidification module 100. It can include color light, light intensity, and the direction of light in such adaptations matters. Etc. RGB-LEDs arranged in different positions (compared to the embodiment shown in FIG. 1), such as color or plural colors, the facilities of the respective light sources with different types and adaptability, particularly achieve this can do. When viewed, it is possible to further modify the parameters of the optical interface 116 in order to best harmony with specific humidification chamber 120 which is connected to the humidifying module 100. For example, preferably the specific color translucent humidification chamber 120, by adapting the emitted light, information transfer information provided by the optical interface 116 is improved. Also, for example, the position from which the optical interface 116 emits light, the direction of the emitted light, can be changed to match the particular geometry of the humidified chamber to be illuminated. The result is improved humidification chamber illumination, information transfer and improved recognition .

Depending on the preferred structure of the humidification chamber, in particular provided by the optical interface 116, triggered it is possible to enhance the effect of flashing the light emission of the illuminated chamber for optical signals, and / or, the effect is applied Depends on the humidification concept being used . For example, for other humidification concept moves countercurrent humidifier or liquid, light reflection interfaces to change, improvement in visibility is achieved by a liquid moving in particular. To attract the attention of the user, because it is particularly suitable, Such dynamic lighting, there are certain advantages. Similar effects can be achieved by dynamically emitting light directly from the optical interface 116.

The optical interface can be or constitute an optical sensor for sensing an optical signal that can be processed by the controller.

Information reached transfer may include warming-up, operating temperature, information about the operating parameters such as operating mode. In addition, the present technology advantageously allows intercommunication with alarm signals indicating, for example, power shortage, dampening liquid shortage, overheating, and the like.

Preferably, each piece of information is conveyed using a color or color intensity code as well as a signal rhythm. Preferably, the green light is applied to indicate normal operation and temperature. Yellow light can be applied to indicate warm-up.
Red light can be used to indicate an error, or it can be used in combination with light of a desired color. A blinking or blinking light such as a blinking or blinking red light can be used for the error message. In some embodiments, humidifier Ki out to suppress the color of light according to approaching the temperature, Shirezu be user does not desire that shines light bright continuous, initially, so bright, then accurate When it reaches a certain temperature, it can disappear. However, any combination of light and light rhythm can be used. According to a preferred feature, the device is adapted for the user to set the color and intensity of the lighting, for example preset 2 to 30 different color palettes, eg 20 colors , eg blue Can be set to a color such as green or white. According to a preferred feature, the color does not change during normal operation, but can change in the case of an alarm . The warning signal can be distinguished by an intermediate priority alarm (for example, visually recognized by blinking with the maximum intensity in the color set by the user) or a highest priority alarm (for example, visually recognized by blinking red ). it can. Both warnings can be synchronized with warning LEDs such as yellow or red on the device. In the embodiment, the color illumination is configured by a user-set combination of several colors, color patterns , and intensities, and preset colors, color patterns, and intensities.

According to an embodiment, the optical interface 116, the humidifying module control device, based on the sensed signal, is configured to evaluate the temperature information of the water level and humidifying liquid humidifying liquid, emitted from the optical sensor An optical sensor capable of detecting light reflection from a specific optical signal is provided.

In some embodiments of the present technology, overheating of the heated tube can be prevented, for example, in the areas of artificial respiration and nasal continuous positive pressure respiratory therapy (CPAP) in the treatment of sleep disordered breathing. Here, the present technology particularly preferably provides non-therapeutic control and failure prevention algorithms (methods and devices) not related to so-called therapy.

One preferred feature corresponding to this technique is preferably based on inferences about whether there is a gas flow through the tube due to the temperature characteristics of the measured response when the heating power changes rapidly. Preferably, the temperature is measured by a temperature sensor located behind the tube heating area when viewed from the direction of flow of the gas. To achieve this, preferably a temperature sensor is placed at the end of the patient's inspiratory tube, and a blower, humidifier or controller is applied to each temperature change pattern and the temperature to change in said heating power. Measure the response characteristics, evaluate the temperature response characteristics, and preferably a predefined operation such as warning or repetition of the process after a predefined time based on the evaluation Adapted to start up.

  By convention, preferably the heating of the tube is interrupted in order to make a heat measurement by means of a temperature sensor. However, preferably, interrupting heating to make a temperature measurement lasts only a few milliseconds and has little effect on the temperature of the breathing hose. Such a very short interruption of heating during temperature measurement has certain advantages in the accuracy of temperature measurement and measurement decoupling. Such time to measure temperature while interrupting hose heating is shorter than 100 milliseconds, and preferably lasts for 10 milliseconds or less.

Preferably, such an algorithm is applied only for systems operating in steady state. The algorithm can include additional steps to consider a standard situation that in particular ensures that the system operates in a steady state and can estimate the presence or absence of gas flow with a high probability. Such a preferred control algorithm is shown in the flowchart of FIG.

Such a control algorithm is activated when the system or method is started, for example, when gas begins to flow and tube heating is activated. As can be readily appreciated, the warm-up time, desired operating parameters are not yet met. Thus, preferably the system has been running the algorithm starts foreseen for a particular time delay. During such a delay time, no pre-defined heating pattern is applied to assess the presence or absence of gas flow. Preferably, in particular, unstable systems are estimated not to allow reliable conclusions. However, it is preferably operating at such a delay time lasting about 15 to 20 seconds, preferably 30 to 60 seconds. In step 200, the control unit performs a temperature measurement to evaluate whether the actual temperature is greater than or equal to the expected target temperature based on the applied heating power. If this is YES, it is assumed that there is a gas flow (see step 220). Here, even if there is no actual gas flow, an actual temperature that is equal to or higher than the target temperature specifies a safe mode and consequently allows a gas flow to be assumed. .

If the actual temperature is lower than the target temperature, it is assumed that there is no gas flow and the procedure moves to step 210. Here the temperature gradient of the temperature sensor is measured and compared with the expected gradient when there is a gas flow. If the slope or rise in temperature, equal to or greater than the temperature gradient or increase in the threshold of the preset gas stream temperature (GradientGasFlow), that the flow of gas there is assumed (see step 240). A preferred slope threshold is in the range of about 1 ° C./10 seconds to about 1 ° C./20 seconds. Alternatively, it is evaluated whether the actual temperature is greater than or equal to the target temperature plus the temperature difference (step 210). The temperature difference is an acceptable value, for example about + 2 ° C., preferably + 1 ° C., which may be 0 ° C. If this is YES, it is estimated that there is a gas flow (see step 240).

If the condition for step 210 is not met , the process proceeds to step 230 where it is evaluated whether the temperature gradient or decrease is less than or equal to the temperature gradient or decrease assumed in the absence of gas flow . Such an assumption is based on a threshold of 1 ° C./10 seconds. Although the threshold of the gradient are mentioned with respect to step 210, such an assumption and the threshold is changed depending on the environmental conditions such as ambient temperature, gas flow rate and the target heating temperature. Preferably, the threshold is based on the normal operation that is assumed in the flow of average ambient temperature and normal gases. If it is this condition is achieved, it is assumed there is no flow of gas (see step 260). As a result, heating may be stopped . After a certain time interval, preferably about 60-180 seconds, preferably about 120 seconds, which can vary based on the specific situation, a predefined heating impulse or cycle is applied and the temperature as described above. Response is measured. As will be readily appreciated, such a heating cycle is configured to ensure that no overheating occurs even in the absence of gas flow .

If the conditions for the step 230 is not achieved, the process proceeds to step 250, the sensed temperature gradient or lower That threshold (GradientLimitN) above, or less than the upper limit i.e. the threshold (GradientLimitP) is evaluated. In other words, it is evaluated whether the measured temperature gradient is in a predefined range , preferably +/− 0.3 ° C./10 sec or +/− 0.15 ° C./10 sec. If the condition of step 250 is not achieved, the preset time interval starting from the time of the first question of step 250 is resumed (step 280) and after a predefined time, eg, 180 seconds has elapsed. The procedure of step 250 is repeated. In such situations, high temperature gradients, is preferably not a 0, expected that the gas flow takes place.

Step 250 condition is achieved about, if not over time intervals, the procedure of step 250, after a time predefined as above has elapsed, it repeats. If the condition for step 250 is achieved and the time interval is over, it is estimated that the system is operating in steady state. In particular, where the gradient of the measured temperature is low. This relates to the risk of missing gas flow and tube overheating . Here, and the heating cycle algorithm that senses the temperature response curve measured by the temperature sensor, which causes the temperature change of the flowing gas defined in advance, can be predefined or in the situation (ambient environment or setting) It is operated repeatedly at intervals that change accordingly . As mentioned above and as will be apparent to those skilled in the art , the applied heating impulse is negative or positive , i.e., includes an increase or decrease in heating power, depending on the situation.

While the above algorithm is running, the system can be turned back at any time if certain conditions suspected of having gas flow are met (see above discussion of unstable gas flow).

Preferably, the applied algorithm and evaluation are based on an average control output. Preferably, where the heating pattern spawning to achieve a jump which can be measured in the gas temperature during a certain time interval the heating of less than 40%, heat of more than 50% during the time interval Including interruptions . As will be readily understood by those skilled in the art, specific temperature differences, temperature rises and falls, gradients, heating cycles, intervals for interrupting heating are, for example, hose length, hose diameter, gas flow, ambient The situation depends strongly on the individual breathing pattern of the patient. Also, as will be readily understood, the concept can be applied to a breathing hose, but is not necessarily connected to a humidifier.

This concept simply and advantageously guarantees that there is a gas flow in the tube, resulting in an easy, reliable, cost-effective means of overheating the tube and the risk of overheating or a warning signal if, and / or may be or perform warning operation.

The algorithm can be applied by a separate control device connected to the hose, as well as by the control unit of an associated device such as a blower or humidifier described further below. This includes single or double hose devices, and the method can be applied to one or both of these tubes.

To assist in preventing the formation of condensate, controlled heating respiratory tube (described in utility model DE 20 2005 008 156US) is, to a temperature adjustable level of the wall surface of the breathing gas and the tube by at least one temperature sensor As a result, condensate formation can be suppressed and reduced.

Consists of control units.

In one embodiment, an apparatus is realized that allows the controller to select different heating stages.

In some embodiments, when the heating tube having a temperature sensor is connected, are allocated to the target temperature of each of the adjustable heating stage it is defined.

In some embodiments where a heating tube without a temperature sensor is connected, each adjustable heating stage can be assigned to the heating power to be output intermittently . There, this assignment is either stored in the control unit, or is determined according to the ambient temperature should be measured in any more temperatures in a low environment increases the level of heating power, and vice versa .

In one embodiment, the controller detects an interrupted or newly generated gas flow by analyzing the temperature signal response when the electrical output is temporarily changed after resting, Next, heat storage is prevented by reducing the average heating power sufficiently , or it is automatically activated when gas begins to flow again.

  In an alternative embodiment, a gas flow interruption or gas flow occurrence is detected by measuring the electrical input of the respiratory treatment device.

  In certain embodiments, gas flow interruptions or gas flow occurrences are detected by additional measurement of gas volume flow in the tube, preferably by a heated sensor element.

In one embodiment, the status of the device (no gas flow → standby / gas flow → heating) is preferably signaled optically in the control / operation part.

However, in order to allow laser welding of two parts, preferably plastic, one of them must absorb the laser in order to be able to weld the two parts together. If the humidifier parts are made of laser-adsorbing material, the visual and aesthetic results are unsatisfactory, but the structural integrity of the humidifier lid welded to the humidifier sidewall is satisfactory It turns out that the result is obtained. In particular, the color of the material of the laser adsorbing humidifier component has been found to change, which can adversely affect the visual and aesthetic appearance of the final product. This may be negligible for colored, non-transparent or non-translucent humidifiers, but it allows the market to accept transparent or translucent humidification chambers In order to do so, it has a severe negative effect. As shown in the embodiments of the present technology , the lid is welded , such as a humidifier lid made of a laser transmissive non-adsorbent material and a side wall of a humidifier made of a transmissive non-adsorbent material. It has been found that a humidifier component is provided. In particular, in order to weld two parts that are both non-adsorptive to laser energy, a laser adsorption sheet is provided between the two parts. Preferably, the laser adsorbing sheet is positioned between the humidifier lid and the humidifier component, closely following the shape of the contact area between the humidifier lid and the humidifier component. Next, laser welding is applied to weld the lid of the humidifier and the humidifier parts together, including the laser suction sheet inserted between them. This enables an efficient, efficient, reliable and inexpensive production of the humidification chamber.
